In preparation for Teen Wolf's season 3b, and learning that Arden Cho (Pretty Little Liars) will play Kira, a high school girl who will possibly be the Kitsune, I did some research on the subject.
As far as we know, Kira is a high school student at Beacon hills high and is of Japanese and Korean descent.
A Kitsune is the Japanese word for fox. which will play nicely into the world of teen wolf.
Kitsunes are described, in some stories as highly intelligent and having magical abilities. Which will be awesome. More magic is never enough.
And then there is the fact that they can assume the human form. But will the Kitsune take the form of Arden Cho and cause trouble or help the town of Beacon Hills?
In other tales, A Kitsune is usually portrayed as a lover, most to the human male. This would mean that they always take female form. Again, Arden seems to fit this. and while she comes to town, the thought that I had was 'who is she there for? Derek? working for someone or what?'
